Patented Jan. 15, 1935 RADIO PATENT o F cE CABINET Arthur T. Murray,Springfield, Mass., assignor to I Unite d American Bosch CorporationSpring field, Mass., a corporation of New York I I I ApplicationDecember 23, 1933, Serial No. 703,765 r 2 Claims.

vTheinvention relates'to radio cabinets, and particularly to thosehaving means for permanently supporting a radio chassis in an inclinedposition therein in such manner that'the dials and other controls can bereadily observed and actuated by the user from either a standing orsitting posture.

Heretofore in such cabinets the receiver has usually been mounted fiat,the controls being arranged on a vertical surface. While such controlscan be reached, one cannot easily observe them without sitting orstooping, unless of course the cabinet is placed upon an elevatedsupport.

In this invention I provide such construction that the controls can beseen and actuated both from the front and above the cabinet, in any ofthe usual positions thereof, without the operator assuming any otherthan an upright bodily position or a sitting position, as desired. Forthis purpose the receiver chassis is fixed on a slant in the cabinet andthe controls are disposed on a panel that is inclined in such way thatthey can be readily connected to the movable parts of the chassis.Preferably the cabinet has a folding or sliding member to cover thecontrols when the set is not in use.

The objects and advantages of the invention are clearly set forth in thefollowing description taken with the drawing which shows severalembodiments thereof, but I reserve the right to make changes in detailsnot shown herein but nevertheless falling within the spirit and scope ofthe invention.

On the drawing: I

Fig. 1 is a perspective view of a cabinet according to my inventionshowing the controls in exposed position; Fig. 2 shows the top of saidcabinet with cover closed; Fig. 3 is a vertical section from front torear through the middle of Fig. 1, 40 illustrating the receiver chassisheld in slanting or inclined position in the cabinet; and Figs. 4 and 5are similar sections showing modifications. On the drawings the samenumerals identify the same parts throughout.

The cabinet 1 has adjacent its top, a panel 2 which slopes down fromback to front. This panel may be in depressed position or inset withrespect to the top and front of the cabinet, between a pair oftriangular members 3 at the two sides. The panel has a tuning knob 4 ona shaft extending through it, and has an opening at 5 through which thedial or scale is observable. The panel may also carry additionalcontrols such as knobs or arms 6 for operating other devices in side thecabinet such as switches, volume control,

tone control, etc. The controls 4 and6 are thus mounted. adjacent thetop 7 of the cabinet, but as the panel 2 is inclined, they can easily beseen from the front of the cabinet 1 or from above it, and can beconveniently manipulated, whether the user stands or sitsand whether thecabinet stands on the floor or on a support of ordinary height.

I provide a cover for the panel 2 consisting of a pair of sections 8 and9, the former being hinged at 10 adjacent the upper edge of the panel 2and the latter hingedly connected to the former and carrying a knob 11.Along the front or lower edge of the panel is a narrow horizontalsurface 12 on which the lower edge of the panel section 9 can rest whenthe cover is drawn down over the panel 2. The front of the cabinet hasan opening 13 adjacent a loud speaker inside. When the cover is closed,top 7 is flat and the cabinet is continuous as shown in Fig. 2. When thereceiver is to be used, the cover 8, 9 is raised and folded back to restupon the top 7 as shown in Fig. 1, or against an object standing on therear part of the top. I

To enable the controls to be disposed in conjunction with the slopingpanel 2, the chassis 14 of the receiver is fixed at a correspondingincline in the cabinet 1. Thus the chassis 14 is mounted inside thecabinet on a slanting base or support 15 supported by triangularprojections 16' secured to the inner face of the front of the cabinet,as shown in Fig. 3. These triangular projections may be adjacent eachside of the cabinet, and the chassis 14 bearing all the necessary partsof the receiver is permanently secured to support 15. The shafts whichare actuated by the knobs 4 and 6 extend through the panel 2 into thereceiver. The base 15 and panel 2 are hence substantially perpendicularto each other. As illustrated in Fig. 3 the loud speaker 17 can besecured to the front of the cabinet 1 around the edges of the opening13. The speaker is thus secured adjacent a highly damped section 'of thecabinet front wall. Vibrations therein are greatly reduced and arecorrespondingly lessened in the side walls and receiver chassis. Animproved baffle is formed for v the speaker and tube microphonics areeliminated in general.

In Fig. 4 the loud speaker is mounted upon an aperture'd verticalsupport 18 which may be affixed to the lower edge of the base 15 and tothe bottom of the cabinet a short space behind the opening 13.

In Fig. 5 the cover is made up of the sections 8' and 9, the connectededges of which are hinged. The main section 8' is not hinged to thecabinet but rests, when the cover is in closed position, on the top of aguide 19 at the rear of the chassis. This guide is parallel with anotherguide 20, and the two are joined at the bottom to form a pocket intowhich the cover can be pushed to expose the control panel 2. The covercan be withdrawn by pulling on the knob 11 and moved into position overthe panel 2, suitable stops (not shown) being carried by the section 8to engage projections at the top of the guides 19 and 20 to limit themovement of the cover. The base 15' is extended at a slant towards thebottom of the cabinet and on the rear face thereof the speaker 17 isattached around the opening 21.

As shown in Figs. 3 and 4, the top 7 of the cabinet has a dependingelement or strip 20 to support the rear end of the sloping panel 2, theforward end being aflixed in any suitable manner to the front of thecabinet 1. In Fig. 5, the rear edge of the panel 2 may be secured to theguide member 19.

For the sake of clearness, the cover 8, 9 and the base 15 in Fig. 3, thepanel 2, base 15, speaker 17 and member 18 in Fig. 4, and the base 15and speaker 17 in Fig. 5 are shown in elevation. In Fig. 4, the tubesand other parts are omitted from the chassis 14.

It will be apparent that many changes and modifications may be made inthis invention by any one skilled in the art without departing from thespirit and scope of the invention as defined by the following claims.

Having described the invention, what I claim is:

1. In a radio cabinet, a chassis support extending downwardly at anangle from the vertical, a receiver chassis mounted on said support, acontrol panel mounted in said cabinet adjacent said chassis andpositioned at right angles to said support, brace means cooperating withan adjacent wall of said cabinet for maintaining said support in angularinclination, and a loud speaker mounted upon said support below saidreceiver chassis.

2. In a radio cabinet, an inclined control panel, a chassis supportsecured in said cabinet at substantially a right angle to said panel andinclining downwardly therefrom, a receiver chassis mounted on saidsupport, brace means maintaining said support in angular inclination anddirecting the weight of said chassis and support against the front wallof said cabinet, and a loud speaker mounted in the lower front wall ofsaid. cabinet directly below said receiver chassis.
